Preheat the oven to 390°F / 200°C and line a flat baking pan with baking paper.
Arrange the cauliflower florets on the pan and drizzle with two tablespoons of olive oil.
Season with a bit of salt and black pepper and roast for about 30 minutes until tender inside yet crispy and slightly golden outside and around the edges.
Transfer in a blender or food processor with the remaining olive oil, tahini garlic, lemon juice, salt, and paprika and process to get a thick hummus, adding water as needed to achieve the desired consistency.
Serve at room temperature with veggie sticks or your favorite keto chips, crackers, and breads.
